Re: [aspectj-users] using @annotation to select annotated aspects
|
Use @within if interested in joinpoints within an annotated type.
Although without a qualifying type of joinpoint, it will match a lot
of stuff (including the call):
===
Join point 'staticinitialization(void Test2.<clinit>())' in Type
'Test2' (Main.java:16) advised by before advice from 'Test1'
(Main.java:12)
Join point 'constructor-execution(void Test2.<init>())' in Type
'Test2' (Main.java:16) advised by before advice from 'Test1'
(Main.java:12)
Join point 'field-get(java.io.PrintStream java.lang.System.err)' in
Type 'Test2' (Main.java:18) advised by before advice from 'Test1'
(Main.java:12)
Join point 'method-call(void
java.io.PrintStream.println(java.lang.String))' in Type 'Test2'
(Main.java:18) advised by before advice from 'Test1' (Main.java:12)
Join point 'adviceexecution(void Test2.ajc$before$Test2$1$33a682())'
in Type 'Test2' (Main.java:18) advised by before advice from 'Test1'
(Main.java:12)
Join point 'initialization(void Test2.<init>())' in Type 'Test2'
(Main.java:16) advised by before advice from 'Test1' (Main.java:12)
Join point 'preinitialization(void Test2.<init>())' in Type 'Test2'
(Main.java:16) advised by before advice from 'Test1' (Main.java:12)

No, @annotation() matches on the subject of the joinpoint. At the
call joinpoint to println, the subject is the method being called,
that method is not annotated with Annotation2.
